WebMD's got advice on choosing the right walking or running shoes for your feet, with neat tips like these:

One way to determine your foot's shape is to do a "wet test"—- wet your foot, step on a piece of brown paper and trace your footprint. Or just look at where your last pair of shoes shows the most wear.

Your wet footprint will reveal how high your arches are and what kind of shoe you should purchase. This one's good to keep in mind too:

Shop toward the end of the day. Feet swell over the course of the day; they also expand while you run or walk, so shoes should fit your feet when they're at their largest.
